Background to Portcullis House

A space audit of the whole parliamentary estate, carried out in the late 1980s by Michael Hopkins and Partners (MHP), revealed an urgent need for more than 200 offices for MPs and a new suite of select committee rooms.

Earlier expansion schemes incorporated listed nineteenth century buildings on Bridge Street and Victoria Embankment but after the passing of the London Underground Act it became clear that it would be necessary to clear the whole corner site to build the new Jubilee Line station.

This opened up the possibility of a substantial new, freestanding building and the creation of a secure parliamentary campus extending as far as Parliament Street and Richmond Terrace.
